Python: Types of Function

In Python, there are mainly three types of function:

• Built-in functions: The built-in functions are those functions that are pre-defined in Python such as help() to ask for help, min() to get the minimum value, print() to print an object to the terminal.
• User-Defined Functions: The user-defined functions are those define by the user to perform the specific task.
• Anonymous functions: It is also called as lambda functions because they are not declared with the standard def keyword.

 Python function may define with or without parameters, and a function may or may not return a value. It entirely depends upon the user requirement .As per our requirement, We can define the User defined functions in multiple ways.

• Python Function with no argument and no Return value.
• Function with no argument and with a Return value.
• Python Function with argument and No Return value.
• Function with argument and Return value.
